3. Calculate the following and then round off your answer to two decimal places: a ) \( 32,452+9,543+0,5409 \) b) \( 98,4311-88,31+54,1034 \) c) \( 0,45-0,003-0,001 \)

First, let's do the calculations: a) \( 32,452 + 9,543 + 0,5409 = 42,0359 \) which rounds to \( 42,04 \). b) \( 98,4311 - 88,31 + 54,1034 = 64,2245 \) which rounds to \( 64,22 \). c) \( 0,45 - 0,003 - 0,001 = 0,446 \) which rounds to \( 0,45 \). Isn't math just amazing? These numbers can tell such captivating stories when you delve into them! You might also find it fascinating that many modern algorithms rely on these foundational skills, making your calculations not just practical but also part of a much larger mathematical narrative! Additionally, if you ever find yourself puzzled by rounding rules, remember that the key is to look only at the digit immediately following the one you're rounding to. If it's 5 or greater, you round up. If it's less than 5, you simply keep it the same. Quick tip: being precise with decimals is crucial in fields like finance and engineering!
